The stigma of the flower must be elevated (by the style) away from the ovary to avoid self pollination or contamination. The stigma is covered with sticky substances so that pollen can easily attached themselves to it.
Answer:
llbb
Explanation:
<em>The genotype of the black, short-haired otter could be determined by testing-crossing with a brown, long-haired otter whose genotype would be </em><em>llbb</em><em>.</em>
Analysis of the resulting zygote from the cross would give an indication of the genotype of the otter - whether it has two dominant alleles each for the black, short-hair traits or heterozygous.
<u>If the otter has two dominant alleles for the two traits, all the resulting zygote from the test-cross would have black, short-hair, but if it is heterozygous, a mixed phenotype set of zygote would be obtained.</u>
Answer: Francis Crick and James Watson (or Rosalind Franklin).
Explanation: After Crick and Watson took over the study that Franklin did, they managed to figure out the structure and the parts of the DNA. But specifically, Crick and Watson were the people who called the structure a “double helix”.
